GUIDE FOR SEWING- MACHINES.

Application filed May 23, 1923.

.To all 11i/10m it may concern.'

lie it known that I, lVAUrnn D. TURNER, a citizen of the United States,residing at l/Vaco, in the .county of McLennan and State of Texas, haveinvented certain new and useful Improvements in Guides for SewingMachines, of which the following` is a specification, reference beinghad to the accompanying drawings.

This invention relates to guides for sewing machines andmore'particularly to a guide adapted for use in forming seams whichinclude the use of piping.

A further and more specific object of the invention is to provide adevice of this character particularly adapted for guiding the sectionsof material used in forming casing covers for automobile tires.

A ilurther object oit the invention 1s to provide in tannbination with aguide of this character, a presser foot so constructed that itymaintains the piping against transverse movement with relation thereto.`

rlheee and other objects l attain by the construction and arrangementshown in theL accompanying drawings wherein for the purpose ofillustration is shown a preferred embodiment of my invention and whereinlike reference characters designate like parts throughout.

In the drawings Figure 1 is a plan view showing` the guide constructedin accordance with my invcntion applied to a sewing machinii;

Figure 2 is a section on the lineA QAQ of Figure 1;

Figure il is a perspective of the guide arm detached Figure 4f is asectional view taken through the seam formed; and

Figure 5 is a section on the line 5 Figure 1.

Referring now more particularly to the drawings, the numeral indicatesan attaching plate adapted to be secured to the bed plate 11 of asewingmachine by the securing elements 12 so employed to holdattachments upon the surface of the bed plate. The plate has avertically offset portion 13 which is integrally connected thereto as at14, this offset portion overlying the bed plate 11 of the machine inspaced relation thereto. Adjacent its longitudinal end edge the plate10, and more particularly the oii set portion 13 thereof, is providedwith an iipwardly extending flange 15 having se- Serial No. 640,914.

cured thereto a reclining U-shaped guide member 16, the lower arm 17 ofthe U being slightly spaced from the upper surface of the offset portion13 of the plate and the bight portion 18 thereof being disposed in thesame plane as the free edge 2O of this offset portion. It will be notedthat the edge of the plate 10, iiange 15 and guide member 16 combine toform a body provided in opposite sides thereof with guide channels A andB, the guide channel A being substantially vertically above the channelB so that this body is S-shaped in cross section. Upon the upper surfaceof the upper wall 21of the channel A a plate 22 is arranged, throughwhich are directed securing elements 23 ergaged in the upper arm 9,1 andupon which the plate 22 is vertically movable. Between the heads of thesecuring elements Q3 and the plate 22, springs 241 are disposed,normally maintaining this plate against the upper surface of the arm 21,the outer edge of this plate being provided with a depending flange 25extending adjacent the outer surface of the bight portion of theU-shaped member 1G and slidably abutting' the free edge of the portion13 of the plate 10. It will be noted that this flange 25 forms a guidespace by closing the mouth of the channel B, the ends of this guidespace being open.

Secured to the plate 10 and more particularly to the offset portion 13thereof, as at 27, is a spring member 28, the end of which extends intothe channel A intermediate the arms 17 and 21 of the U-shaped member 16and which is provided at its end with an upturned flange 29 directedtoward the uppermost arm 21 of the U which forms the upper wall of thechannel A, this ilange paralleling the bight portion 18 of the U. Theoffset portion 13 of the plate has further secured thereto an arm 30provided with an angular portion 31 formed at its end with an eye 32. Inthe present instance I disclose this eye as formed by providing a stripof sheet metal formed intermediate its ends to provide the eye andhaving its end portions in slightly spaced relation as indicated at Se,these end portions having their extremities attached to the angularportion 31 of the arm in any suitable manner. The eye 39., and moreparticularly the opening thereof, is in longitudinal `alignment with theend of the guide space B. The flange 25 has the end thereof nentadjacent the eye cut away as indicated at 35,

lll5

and the corresponding corner 'of the offset portion 18 of the plate,indicated at 36, is

slightlv down-heut so that this corner combiiies lwith the flange toform 'a V-shaped mouth 2li into which a piece of cloth may be introducedto lift the flange and plate 22 against the action of the springs 24.

`In Figure 4- I have illustrated the seam which the guide isparticularly adapted to construct. rIhe seam, it. will be noted,includes an under ply 38 of material, an over ply and a beaded pipingstrip 4t). In the completed seam the piping strip has the bead #i1thereof exposed to view. this bead usually being of a di'tlerent colorfrom the under andover plies Z-lts and 239. Since the over pl;Y 59 isvexposed to view, the end portion 33) thereof must he reverted and inthe construction of vehicle tire covers this reverted edge is usuallyglued or otherwise fastened ininosition before the goods is introducedto the machine. In the contruction of the guide the flange 2f) is spacedfrom the adj acent 'tace of the hase of the channel A formed h v thebight portion 18 of the U a distance equal to the distance of themarginal edge ot the over ply Si) and the inner edge o-f the revertedportion 39, The eye of the arm il() is made of such size that itslidably receives the bead 4:1 of the piping strip 41o, the body et?, ofthe piping strip extending into the space 34 provided therefor. From theeye 32 the piping stripis led through the guide space B from end to end,the space between the adjacent faces of the langeQ and iiange 15 formingthe base of the channel A being equal to the double rwidth of the pipingstrip. i The under ply 38Vof material is led beneath the eye 32 of thearm and engaged in the mouth 37 of the guide opening Il, the edge of theunder ply abutting the outer face of the flange 15 beneath thepipingstrip 40. The inner face of the hight portion 1S of the U is in avertical plane corresponding to the inner Iedge of the bead `fl-'l ofthe piping and since the edge of the over ply 39v abnts against theinner face of this hight portion the overply held in such position thatonly the bead l1 of the piping strip is exposed to view.y

By an inspection of the sectional view shown in Figure 2 it will be seenthat when the materials are so arranged the edges of the piping strip40, under ply 39 and the reverted portion 89 of theover ply 39 arealigned and the goods accordingly positioned for the formation of theseam therein. It will be obvious that the piping strip L10 beingrelatively narrow and aocoriilingly flexible will have a tendency tomove after litting the guide and before engaging beneath the presserfoot d3. I accordingly form the p"""cr foot 48 with a concaved undersuri..ty, this coneau extending longitudinally et the p s Yloot andforming a guide for the feed `of the piping to prevent transversemovement thereof with relation to the under and over plies 38 and 39. Iam aware that heretofore the under surfaces of the presser feet havebeen concaved for various purposes and I accordingly do not claim thisconstruction of the presser foot as new except in the con'ibinationhereinbeforc set forth. f

lllhat is claimed is 1. A guide for use in forming seams comprisingoppositely directed under and over plies, comprising a member S-s'hapedin cross section providing oppositely directed ply edge receivinglchannels, and a rresilient element projecting into one of said channelsand abutting one wall thereof in spaced relation to the base of thechannel.
